A 9 year old patient has a non carious primary maxillary right first molar in infra occlusion. The radiograph shows lack of PDL and a radiolucent area that may be normal resorption. the first premolar is present. The first molar is best managed by:
1. Observation
2. Extraction only
3. Routine extraction and space maintenance
4. Surgical removal and space maintenance

The answer given is OBSERVATION, I want to know, It seems the tooth is ankylosed, so why wont we go for surgical removal and space maintenance?

B) For an extension based removable partial denture, which of the following is most important to maintain the remaining suppporting tissues
1. Using stress releasing clasps
2. Preserving denture base support
3. Limiting eccentric occlusal contacts
4. using plastic teeth

Is preserving denture base support the answer to the second question?
Can some one else also answer this?
 
If there is posterior bilateral cross bite in centric relation, accompanied by a lateral shift of the mandible, a change in midline relationships, and a unilateral cross bite in centric occlusion, the patient also has a

Can u pls ans my ques:
)Pulpectomy and filling a Mnd Molar, where would you most likely perforate?

What has the least root surface area in mm squared?
* Mx Lateral
* Mx Central
* Mnd 1st PM

When dealing with furcation, Guided tissue regeneration best used with Osseointegrated bone graft. Prognosis of tooth with GTR is better in Mx molar than with Mnd molar.
# True or False of each statement

27)Clearance for occlusal rest is determined how?

28 tearing of the flap is MOST commonly
repeated incision in the same place
envelope incision
semilunar incision

when you use use ziinc oxide in a primary tooth what kind do you use
with cataylst
without catalyst
what forcerp do u use for a broken mesial root of a mandibular molar?
crayers
cranes
criers

what type of fracture in tooth will allow complete transillumination of crown? Vert root fract, cracked tooth, craze lines

how to keep distal box of amalgam from being displaced proximally? Proximal retention grooves, converge facial and lingual walls, widen isthmus

hey pri,
thanx
Hi Benny,

Pulpectomy and filling a Mnd Molar, where would you most likely perforate?
ans-pulpectomy
Here he asks where like mesial, distal?

What has the least root surface area in mm squared?
* Mx Lateral-ans
* Mx Central
* Mnd 1st PM

When dealing with furcation, Guided tissue regeneration best used with Osseointegrated bone graft. Prognosis of tooth with GTR is better in Mx molar than with Mnd molar.
# True or False of each statement
first statement true,second statement false
Is it due to more bone formation in mandible or other reason?

27)Clearance for occlusal rest is determined how?
check for occlusion with opposing tooth

28 tearing of the flap is MOST commonly
repeated incision in the same place
envelope incision
semilunar incision-ans
can u tell wy? i think due to its less accessibility

when you use use ziinc oxide in a primary tooth what kind do you use
with cataylst
without catalyst-ans
pls tell wy? coz somewhere i find this ans but one time with catalyst too😕

what forcerp do u use for a broken mesial root of a mandibular molar?

it's because mandibular molars are bifurcated and maxillary molars are trifurcated.so prognosis in mandibular molar is better

that's right because of less accessibility


when you use use ziinc oxide in a primary tooth what kind do you use
with cataylst
without catalyst-ans
pls tell wy? coz somewhere i find this ans but one time with catalyst too

it's because if you use zinc oxide eugenol with a catalyst the roots won't resorb


how to keep distal box of amalgam from being displaced proximally? Proximal retention grooves, converge facial and lingual walls, widen isthmus
ans-converge facial and lingual walls occlusally

I checked studervant and it's given that primary form of retention is by converging the facial and lingual walls occlusally and secondary retention is through retention grooves and occlusal dove tail.


Hope this helps
 
The most logical explanation for causing swelling
beneath the eye caused by an abscessed maxillary
canine is that the
A. lymphatics drain superiorly in this region.
B. bone is less porous superior to the root
apex.
C. infection has passed into the angular vein
which has no valves.
D. the root apex lies superior to the
attachment of the caninus and levator​
labii superioris muscles.

The anatomical landmarks used to help establish
the location of the posterior palatal seal of a
maxillary complete denture include the
A. pterygomaxillary notches and the fovea
palatinae.
B. pterygomaxillary notches and the
posterior nasal spine.
C. posterior border of the tuberosities and
the posterior border of the palatine bone.
D. anterior border of the tuberosities, the
palatine raphe and the posterior border of​
the palatine bone.

In the mandibular first premolar, the occlusal
dovetail of an ideal disto-occlusal amalgam
preparation is usually not extended into the mesial
fossa because of the
A. small lingual lobe.
B. large buccal cusp.
C. large buccal pulp horn.​
D. prominent transverse ridge.

In pin-retained restorations, the pin holes should
be parallel to the
A. long axis of the tooth.
B. nearest external surface.
C. pulp chamber.​
D. axial wall.

 
Hi pri,
thanx, regarding last ques. i checked in strudavent too that yes walls converge occlusally to give primarry retention but here he asks to prevent proximal displacent so for that its grooves. hope u got my point.
And regarding ZnO eugenal, if catalyst doesn't increase resorbtion, couldn't get again.
some more ques pls:

q)many porosities in acrylic denture; why? Over packing acrylic, inaccurate powder/liquid ratio, leaving too much flash, heating temp too high
not sure if it should be high temp?

2. when to do bone graft for alveolar cleft? Before primary canine erupts, before permanent canine erupts, after permanent canine erupts, when do orthognathic sugery

3. for taking the impression 4 an implant what do u do first
chk the tray 1st to see its fit
put the coping with acrylic resin
put the coping first
wat is coping??

4. what is not an indication for restoring class V abrafaction?
Sensitivity,
esthetics,
prevention of decay,
prevention of further structure loss,
restoring physiological contour


5.hand rolled acrylic tray can't be used for 24 hrs why?
Distortion,
needs to dry,
adhesive won't stick

Pan showing lucency going inferior over the body of mandible close to the angle. Informed the patient was involved in an accident. Identify the lucency
a. pharyngeal airspace
b. fracture
c. artifact-retake radiograph

There are more detached plaques within supragingival plaques that subgingival plaques. The detached plaques within subgingival area are the ones that are more toxic to tissue than attached plaques
a. both statements are correct
b. the first statement is correct but not the second
c. the first statement is wrong, but the second statement is correct
d. both statement are wrong
I read there there is loose( detached plaque subgingival) which cause aggressive periodontitis but ans was not matching?

Palatal expansion device does not need a labial bow because
a. labial bow is not rigid enough
b. labial bow would limit the expansion effect
c. labial bow is not functional in this cases

Which of the followings is not an advantage of resin based GIC over water based GIC?

What is the distance between an implant and cej?

Occlusal space of an implant?


How do you place an implant in the ant part of maxilla
 
What is the distance between an implant and cej?

Occlusal space of an implant? no idea, answer this please


How do you place an implant in the ant part of maxilla



What is the distance between an implant and cej? is it sumthing related to biological width?

How do you place an implant in the ant part of maxilla?
if the question is in relation to anatomical structures, then, 1.5mm is the minimum distance between any anatomical structure and implant.
 
how deep you floss? 1, 2, 3 mm deep in gingival sulcus?

how deep you postion bristle in gingival sulcus

not sure if it should be high temp?
answer-heating temperature too high

2. When to do bone graft for alveolar cleft? Before primary canine erupts, before permanent canine erupts, after permanent canine erupts, when do orthognathic sugery
answer-before permanent canine erupts

3. For taking the impression 4 an implant what do u do first
chk the tray 1st to see its fit
put the coping with acrylic resin
put the coping first---answer
wat is coping??
the cover screw on the implant is removed and the impression coping is screwed into the implant and then an impression is taken.this impression coping is loosened prior to removing the impression from the mouth.then the cover screws are replaced back on the implant

Hi pri,
thanx, regarding last ques. i checked in strudavent too that yes walls converge occlusally to give primarry retention but here he asks to prevent proximal displacent so for that its grooves. hope u got my point.
And regarding ZnO eugenal, if catalyst doesn't increase resorbtion, couldn't get again.

Hey Benny,
this is what I found on sturdevant,
the distal pit area provides dovetail retention form ,which may prevent mesial displacement of the completed restoration.
the occlusal convergence of the facial and lingual walls and the dovetail design (if needed) provide sufficient retention form to the occlusal portion of the preparation.
the occlusal convergence of the mesiofacial and mesiolingual walls offers retention in the proximal portion of the preparation against displacement occlusally.To enhance retention form of the proximal portion,proximal locks may be indicated to counter proximal displacement.

Thanks,so what you said is right.but i was thinking that we normally don't place the proximal grooves in all the amalgam restoration.that's why i was thinking of convergence of the walls.But since it is clearly mentioned that it will prevent proximal displacement so retention gooves will be the answer.Thanks again
and about the second question,they use the ZnO Eugenol without catalyst because the one with the catalyst will not resorb when the tooth resorbs that's what I think
 
Hey pri,
thank u, I cheked that ques of translimination too, its ans should be craze line not crack for sure.
and regarding most common incision, that is envelope flap is right but was thinking its mostly used in perio, here he asks for oral surgeons so can we say z incision which is mostly for frenctomy, 3rd molar any idea??
some more ques pls:
with a modified Widman flap you mostly reduce bone by
a. adapt the flap margin
b. osseous restructuring
c.removal of infected osseous tissue
d removal of malignancy tissue

2.where can you get dental literature
library of congress
ovid
lexus
dental abstract
dental online
3. what instrument is used to trim the facial box of a class 2 prep
bibeveled
bi angled

4.what does Ma does to intensity when doubled
half
one 8th
nothing

5.how do u test a tooth to differentiate between chronic perio and supperative perio
cold test
percussion
EPT---
we can say only precussion here wat i think, but then chronic periodontitis is also TOP positive, isn't it?
6. class II composite what margin deteriotes first?a) occlusalb) lingual c) faciald) interproximal

7. Which is better to detect brain tumors? CT, MRI, Waters, Reverse- Townes (CT)

Most caries in kids
is it pit & fissure?

ECC- who has most Early childhood caries?

27)how do you determine the length of the post stem? Patients age anatomy, tuberosity, tissue conditioning WHAT IS STEM???

Thank u sildent, do u know 1.wat's for dental abstarct and lexus. regarding abstracts it also show all dental articles as ovid medline?

2.And yes enamel hatchet is single beveled, is it biangled then?
3.If highest caries rate among adults is in whites?
4. If quinidine is used for both atrial & ventricular arrthmymia? Coz i read in book that its used for both but decks show for atrial only??
5. wen do we do serial extraction, if space deficiciency is more than 4mm or upto 10mm, as these r two different ques in ortho decks?
6. For my ques of brain tumors why not CT scan best?
7. wat is absent in toothpaste: stannous flouride or APF? deck say now no stannous flouride is used in dentrifices so wat will be ans, i don't think APF is used either?

hey Benny,
the question about transillumination was that the fracture was through the crown,isn't craze lines limited within the enamel
 
Hi Benny,

with a modified Widman flap you mostly reduce bone by
a. adapt the flap margin
b. osseous restructuring---answer(not sure)
c.removal of infected osseous tissue
d removal of malignancy tissue

2.where can you get dental literature
library of congress
ovid--answer(I think same question is there in II-L or II -M)
lexus
dental abstract
dental online
3. what instrument is used to trim the facial box of a class 2 prep
bibeveled
bi angled
I think it should be bin angled and not bi angled

Enamel hatchets are also used.

4.what does Ma does to intensity when doubled
half
one 8th
nothing

is the distance doubled here or mAs is doubled?
5.how do u test a tooth to differentiate between chronic perio and supperative perio
cold test
percussion---answer
EPT---
we can say only precussion here wat i think, but then chronic periodontitis is also TOP positive, isn't it?

I don't think chronic periodontitis is tender to percussion but when it turns into a periodontal abscess ,it is tender to percussion

6. class II composite what margin deteriotes first?a) occlusalb) lingual c) faciald) interproximal
answer-interproximal

7. Which is better to detect brain tumors? CT, MRI, Waters, Reverse- Townes (CT)
don't know

Most caries in kids
is it pit & fissure?
pit and fissure

ECC- who has most Early childhood caries?
answer-hispanics

27)how do you determine the length of the post stem? Patients age anatomy, tuberosity, tissue conditioning WHAT IS STEM???
even I can't understand this question

 
Hi Pri,
That ques was which cause full translumination of tooth, and its craze line which led to it.
Here 2nd ques is ovid but i read similar ques with ans abstract, do u know wat's for dental abstract then? It also include all dental articles like ovid.
For ques 3, it was spell mistake, its bin angle but do u know if enamel hatchet is bin angle?
If class 2 composite will not detriote occlusal first due to mastcatory forces?
And 4th ques is yes its milliampere not distance.

I was checking online and the answer is ovid medline ,because dental abstract ia a bimonthly publication from elsevier which provides only general and speciality dentistry abstracts which ovid medline has the complete literature

Enamel hatchet is not binangle but it is a kind of a chisel just like binangle

I think about the question for class 2 composites it's still interproximal because most of the recent composites like nanocomposites have comparable strength to amalgam and the main problem with composites nowadays is secondary caries and bulk fracture

and about the question for intensity and mA ,was there any option doubled because I read that intensity is directly proportional to the mA.so i presume if mA is doubled ,intensity will double but I am not sure.
 
Thank you Pri, there was no option of doubling mA for intensity, may be missing.
